SMOKE-FLUE AND CH'IMNEY LINING.

Speciication of Letters Patent. Patented Sept. 10, 1918.

Application med september 15, 1917. serial No. 191,584.

To all whom it 'may concern.' l

Be it known that'I, JAMES C. D. WEEKS, a citizen of the United States,residing at Chea'side, in the county of Northampton and State ofVirginia, have invented new and useful Improvements in Smoke-Flues andChimney Linings, of which the following is a specification.

This invention relates to masonry smoke Ilues and chimneys, and itsobject is to provide the same with a novel and improved shield to guardagainst fires from flames or sparks finding their way through cracks orcrevices opening through the chimney or flue from the interior thereofto the outside and exposing the surrounding partitions or other buildingelements to the flames, sparks or intense heat escaping through suchcracks or crevices from the interior of the flue.

The invention also has for its object to provide a shield of the kindstated which is of simple construction, and can be readily put up, andwhich is securely held in place.

The objects stated are attained by means of a novel combination andarrangement of parts to be hereinafter described and claimed, and inorder that the same may be better understood, reference is had to theaccompanying drawing forming a partof this specification.

In the drawing,

Figure 1 is an elevation partly in section,l

showing the application of the invention;

Fig. 2 is a horizontal section of the line 2-2 of Fig. 1;

Fig. 3 is a perspective view showing a fragment of the lining, and

Fig. 4 is a perspective View showing the base member of the lining.

Referring specifically to the drawing 5 denotes a masonry chimney orflue having a central flame and smoke passage 6, with side openings 7leading therefrom to receive the pipes or iues from the various stovesin the different rooms on the several floors ofthe building. The oors ofthe building are shown at 8, and the roof at 9.

In the passage 6 is mounted a shield or lining of metal to prevent theescape of iames or sparks through cracks or other defects in thebrickwork. This lining is made up of a plurality of rectangular casings10 open at the top and bottom and assembled in superposed relation, oneon the top of the other so as to form a continuous flue extending fromthe bottom to the top of the passage and lining the same. Certain onesof these casings are provided on one side with vlaterally projectingthimbles 11 extending into the side openings 7 for attachment of thestove pipes or flues.

On opposite sides of each casing l() are fastened guide straps 12 forretaining members, whereby the casings are centered and held in place inthe passage 6. Each of these members comprises a bar 13 having a lateralbend 14 at one end. The bar 13 forms the shank of the retaining memberand seats beneath 'the guide 12, whereas the bend 14 extends into thewall of the flue 5 and is bricked up. The bar 13 depends from the bottomof the casing 10 a suliicient distance to lap the next casing below, andthe several casings are therefore securely held in aline- Inent. As theretaining members are adjustable lengthwise in the guides l2, they canbe set to bring the bends 14 into any mortar joint at the side of thecasing.

The bottom casing 10 has outstanding base ianges l5 which are bricked upin the same manner as the retaining members hereinbefore described. I

The shield affords complete protection against fires from a defectiveiiue, and it can be readily applied when the flue is being built.

I claim The combination with a chimney or flue; of a lining thereforcomposed of a series of casings assembled in the iue in superposedrelation, and retaining members for the casings composed of angular barsconsisting each of a shank and a laterally outwardly extending part,said members being mounted on the sides of the casings and the shanksthereof depending therefrom across the joint between the same and thenext casing, and the outwardly extending parts of the members beingembedded in the wall of the flue, and guides mount-ed on the outer facesof the casings in which the shanks of the retaining members arelongitudinally adjustable.

In testimony whereof I afiix my signature.

JAMES C. D. WEEKS.
